New Feature on Sapere: Our AI Agents Are Transforming Language Learning

On Sapere, virtual tutors support every learner, from the dashboard all the way to the personalized exercises. Always ready with a tip, they never do the work for you.

Imagine you're learning German and a conjugation exercise pops up: "Wähle den Satz im Präsens…". You recognize "Satz" and "Präsens," but "wähle" doesn't ring a bell, and you're stuck. To get past it, you could open a translator in another tab, look it up in a dictionary, or try to guess. Sometimes, you just give up on the exercise.

On sapere.ai, all you have to do is ask your AI agent: "What does wähle mean?" It replies with the infinitive (wählen) and then the translation ("choose"), and you pick up the exercise right where you left off. In twenty seconds, you're unstuck.

This small moment sums up what AI agents are changing in language learning. They're there when you need them, out of the way when you don't, and above all, never there to do the learner's work for them.

A tutor just one click away

On Sapere, the tutor isn't hidden away in a menu. It's right there in the bottom-right corner of the screen, in the form of a small smiling character. A flag shows the language you're studying, and a speech bubble invites you to use it: "Ask your tutor."

One click is all it takes to start a conversation. The tutor introduces itself simply: it can translate sentences, answer your questions about the lesson, and explain the tricky parts.

You can type your message, but you can also talk to the AI agent using the microphone and listen to its answers out loud. That's handy for working on your speaking skills, or simply when you'd rather talk than type.

On the dashboard: a guide to help you find your way

Just created your account and not sure where to start? Right there on your dashboard, the AI agent points you in the right direction and explains each feature. Wondering what the lexical field is for, how your personalized learning path works, or where to find your exercises? The agent explains it all in a few words.

During exercises: a real tutor

Sapere lets you practise with a variety of exercises, such as multiple-choice quizzes, listening comprehension activities, and fill-in-the-blank sentences. Practice is exactly where the agent shows its true value. In the middle of an exercise, the tutor can:

• translate a word, an expression, or an instruction;

• explain a grammar point;

• give an example of how something is used in a real sentence;

• rephrase an explanation that wasn't clear.

In short, it answers anything you'd ask a teacher sitting right next to you.

One language, one tutor

German, Spanish, Japanese… The tutor adapts to the language you're learning, and to its own particular challenges.

Take Marc. He's learning Japanese for work. In the middle of a reading exercise, he comes across 駅. He's seen this kanji before, but he can't for the life of him remember how to read it. He asks the tutor, who replies: "えき (eki), it means 'station'." Then it adds an everyday example to help him remember it.

A little further on, Marc hesitates between two small particles, は and が, which give almost every Japanese learner a hard time. The tutor explains the difference using simple sentences, one at a time.

The agent won't turn Marc into an expert overnight. But he now has a better grasp of the language's nuances!

The golden rule: never give away the answer

Having an AI agent available at all times shouldn't get in the way of learning. A tutor that simply handed over the right answer would be convenient in the moment. But the learner would finish the exercise without having learned a thing. Sapere's agents are designed to do the opposite: they give you the tools to find the answer, not the answer itself.

German example: conjugation

Let's go back to our exercise. You have to choose the correct sentence from "Ich schreibt," "Ich schreibe," "Ich schreibst," and "Ich schreibte." If you ask the tutor which one is right, it won't tell you.

Instead, it will remind you how a regular verb is conjugated in the present tense, with the ending that goes with each person. Then it will let you choose.

Spanish example: ser or estar?

Laura has to complete the sentence "Hoy ___ muy cansada." She's torn between "soy" and "estoy," a classic dilemma. She asks the tutor for help.

It doesn't fill in the blank for her. Instead, it reminds her that "ser" is used to describe what something or someone is in a lasting way (an identity, a personality trait), while "estar" describes a temporary state. Laura remembers that "hoy" means "today" and finds the answer on her own. The bonus: next time, she probably won't need to ask.

Explaining the answer instead of giving it: what learning science says

Looking for the answer yourself takes a bit of effort. And it's precisely that effort that locks learning into memory. Learning science calls this active recall: we remember what we had to work to retrieve much better than what we simply read. That's also why one of the best ways to learn something is to explain it to someone else. We explain the principle of retrieval practice in more detail in our article on the forgetting curve.

An answer you found yourself, you remember. An answer you were given, you often forget by the next exercise. Thanks to the agent's help, learners keep their momentum, and the exercise remains a learning moment rather than a source of frustration.

Evaluations: you’re on your own!

Of course, the tutor isn't available during evaluations. This is a deliberate choice: an assessment should reflect what the learner truly knows, without outside help. It's the only way to get a reliable result, for the learner as well as for their teacher or employer. To make progress, it's important to know your actual level (and a precise one, thanks to the 18-level Sapere scale) so you get exercises that are right for you.

During exercises, you learn with the agent's support (if you need it). During the assessment, you measure what you've really learned, and you may just surprise yourself!

Limitations worth knowing about

AI agents are remarkable tools that add real value to learning. But to make the most of them, it also helps to know their limits.

• They don't replace a teacher. A virtual tutor is great at explaining a rule. But it can't tell that you're feeling discouraged this week, and it doesn't know your journey the way your teacher does. That's why we believe in blended learning, as we explain in our article AI Tutor vs. Teacher: What Really Works.

• They can sometimes be wrong. Like any artificial intelligence, an agent may occasionally give an inaccurate explanation, especially on subtle nuances or very regional expressions. Keeping a critical eye is part of learning, and a doubt always makes an excellent question to bring to class. You can also report a bug directly on the platform!

• The quality of the help depends a little on the question. The more specific the request, the more useful the answer. "I don't understand" will get a general answer. "Why do we say 'estoy' and not 'soy' in this sentence?" will get a targeted explanation. It's a habit worth getting into.

And let's not forget that this help is optional! Sapere's AI agents stay in the background so they don't get in the way of learners who don't need them.

AI agents: a teacher's ally

For teachers, agents are valuable allies. They answer one-off questions between classes, which frees up class time for what really matters: conversation, nuance, and support. They can also generate exercises or bring up a student's level to help with follow-up.

And since agents never give away the answers and step aside during assessments, teachers can trust the exercise results they review. What they see reflects their students' real level.

AI handles the small everyday questions. The teacher focuses on what matters most.

Sapere's AI agents are tutors available around the clock: they guide without taking over, explain without giving away the answer, and know when to step back at assessment time.

Whether you're learning German, Spanish, or Japanese, they don't replace your effort or your teacher's expertise. They simply make every minute of practice more useful, and a little less lonely.
